L2TP (VPN) for Windows Vista

The procedure for setting up L2TP on Windows Vista is the same as the one for setting up PPTP. The tutorial for the latter can be found here.

However,
you need first to input the correct proxy.sh IP for L2TP, which may be
different from the PPTP one, and you also need to edit the network
properties of the VPN connection, select the Security tab and change the
Type of VPN to Layer 2 Tunneling Protocol with IPsec (L2TP/IPSEC) and
the data encryption to Maximum strength encryption and deselect the CHAP
authentication method. Click on Advanced settings.

Then enter the shared secret "security" in the field entiteld 'Key'.

Then confirm everything and connect as per the instructions for PPTP tells you to.

NB: If you encounter difficulties to connect with L2TP, please try to
switch to OpenVPN. OpenVPN is more reliable, more secure and more
flexible. OpenVPN also allows you to try various ports, including
'discreet' ones such as TCP 443. Below, you will find an aggregate of
useful guides and articles that will help you troubleshoot your
problems, should you have any.

If
you still cannot connect successfully, please open a support ticket and
include either a copy of your logs or a screenshot of your
configuration and encountered errors. Logs can usually be found in
software menus or settings, as well as their directories of installation
(.log or .txt files). If you do not include a log or a screenshot, it
will be hard for us to help you resolve the issues you have with
connecting to our network.
